    This study determined the incidence of groundnut rosette disease (GRD) and genetic diversity of groundnut rosette assistor virus (GRAV, genus Luteovirus) in western Kenya. The diseases is a major constraint of groundnuts in Sub-Saharan Africa (SSA) causing up to % yield losses in severe cases.

Abstract. The major objective of this Third Consultative Group Meeting is to bring together representatives of various research groups involved in research on groundnut rosette virus (GRV) disease to review their research findings and to coordinate plans for future research and cooperation.

Research has shown that plants infected by groundnut rosette virus alone show little or no effect, but that the symptoms of the disease are caused by a satellite RNA co-infection, a subviral agent.

Groundnut plants affected take on a bushy appearance due to Family: Tombusviridae. Rosette has been a constraint to the production of groundnut in the existing farming system which contributes to the poor productivity of this crop. This trial was conducted in the screen-house of IITA Kano station, Nigeria to screen some groundnut varieties to rosette disease.

The following parameters were measured during the trial such as chlorophyll content, plant vigor, disease incidence. The disease is caused by synergistic interaction among groundnut rosette assistor virus (GRAV, genus Luteovirus), groundnut rosette virus (GRV, genus Umbravirus) and its associated satellite RNA (sat-RNA).

The GRAV plays a crucial role in packaging the other two agents for vector transmission, and therefore a key factor in the spread of certifiedneighborhoodspecialist.com: Anthony Simiyu Mabele, Hassan Karakacha Were, Millicent Florence Owuor Ndong’a, Benard Mukoye.

Rosette is the most destructive virus disease of groundnut in sub-Saharan Africa. It is caused by a complex of groundnut rosette assistor virus, groundnut rosette umbravirus and its satellite RNA.

The disease appears to be indigenous to Africa. The disease is thought to have spread to the introduced groundnut from indigenous host certifiedneighborhoodspecialist.com by: Groundnut virus diseases in Africa: Incorporating the Proceedings of the Fourth Meeting of the Consultative Group on Collaborative Research on Groundnut Rosette Virus Disease, Montpellier, France, September / Reddy, D.V.R.In: Coordinated Research on Groundnut Rosette Virus Disease, ICRISAT.
